We construct a regular random projection of a metric space onto a closed doubling subset and use it to linearly extend Lipschitz and $C^1$ functions. This way we prove more directly a result by Lee and Naor and we generalize the $C^1$ extension theorem by Whitney to Banach spaces.

通过随机投影的线性 Lipschitz 和 C1 扩展算子

我们将度量空间的规则随机投影构建到封闭的加倍子集上,并使用它来线性扩展 Lipschitz 和 $C^1$ 函数。通过这种方式,我们更直接地证明了 Lee 和 Naor 的结果,并将 Whitney 的 $C^1$ 扩展定理推广到 Banach 空间。
